Additional Information


It is advisable to make a preliminary running Sprocket, rolling gently for a few hours before you start to trial, to remove excess grease used in the assembly and ensure proper seating of the trigger mechanism. If the pinion is used to trial without having settled before the triggers will not work properly and will jump, damaging the slot and trigger.
